基于地质统计学的DTM空间插值技术研究

RESEARCH ON THE DTM SPACIAL INTERPOLATION TECHNIQUE BASED ON THE GEOLOGICAL STATISTICS

本文针对数字地面模型(D igital Terrain Model)的建模问题,将高程看作区域化变量,应用地质统计学(GS)中普通克立格(简写OK法)研究了1个山区高程空间变异分析及其插值。结果表明:OK法可以进行DTM的最优空间插值,而且可提供插值结果的精度,能满足DTM对高程的精度要求,其插值结果表明OK法可以直接用于DTM的建模。

Looking on to establishing DTM, regarding elevation as zonal variant, using OK method of GS, a montane elevation spaeial variation was studied. Results showed that OK method can be used to do optimum spaeial interpolation of DTM, it can offer the interpo- lation precision and satisfy requirements, it＇s results can be directly used in DTM establishing.
